Many points in the life-history of the clothes moth, Tineola biselliella. 

 Hum., remain unknown, and little information is available on its 

 methods of spread. 



Examination of an entomological collection infested by this pest 

 led to the assumption, subsequently confirmed by breeding experiments, 

 that T. biselliella is less a pest of the preserved insects than of the peat 

 slabs at the bottom of the boxes.

In the azalea house of the palm garden at Frankfort -on-Main some 

 injury to the leaves is done by caterpillars of Gracilaria zachrysa,

A severe infestation of Viburnum opiilns by a Chrysomelid beetle, 

 Galerncella viburni, Payk., is recorded from Hessen. The larvae enter 

 the soil in June to pupate, and the adults emerge in August. Infested 

 shoots should be removed in winter, or the ground beneath the; plants 

 should be disinfected in June or Juty .

In addition to larvae of Endrosis lacteella and Ephestia elutella, 

 found in a sample of cocoa powder from a South German chocolate 

 factory, both larvae and adults of Niptus hololeucus, Fald., were 

 present. This beetle is known to feed on a variety of objects of animal 

 or vegetable origin such as sponges, bones, feathers, brushes, woollen 

 and leather goods, etc. It is a domestic pest in Europe, and difficult 

 to combat. Fumigation with hydrocyanic acid gas (1 volume per 

 cent.) kills it after several hours' exposure. According to Guide it is 

 attracted by damp cloths, so that it may be possible to trap it by 

 means of these.

The tobacco beetle, Easioderma serricorne, ¥., is recorded in a 

 consignment of tobacco from Holland. Fumigation with hydrocyanic 

 acid gas was found effective. With a strength of 1 volume per cent., 

 an exposure of 2 hours is required, or 24 hours at 1 volume per mille. 

 Loose tobacco, cigars and cigarettes withstand 42 hours' exposure to 

 \\ volumes per cent, without showing any trace of treatment or any loss 

 of aroma.
